SAN FRANCISCO October 21, 2020 – Pacific Gas and Electric Company (PG&E) will de-energize certain electrical lines for safety over the course of this evening (Wednesday, Oct. 21) as part of a Public Safety Power Shutoff (PSPS). PG&E is calling a PSPS due to a high-wind event combined with low humidity and severely dry vegetation, that together create high risk of catastrophic wildfires.

Due changes in the weather forecast, the number of customers expected to be impacted has decreased by 31 percent. The PSPS event will affect approximately 37,000 customers in targeted portions of 15 counties.

  • Counties removed from scope include: Lassen, Solano, Stanislaus and Yuba counties.
  • Counties remaining in scope include: Alameda, Butte, Colusa, Contra Costa, Glenn, Humboldt, Lake, Napa, Plumas, Santa Clara, Shasta, Sonoma, Tehama, Trinity, and Yolo Counties.

Customers Notified of Decision to Shut Off Power Wednesday afternoon 

Customer notifications began 48 hours in advance of the shutoff and PG&E continues to update affected customers. Customers were notified this afternoon that the PSPS event would occur and customers who were removed from the scope were notified of cancellation. Lines will be de-energized starting at approximately 8 p.m. tonight and the de-energization process will continue throughout the evening, depending upon location, across the Sacramento Valley, Northern Sierra, and elevated terrain of the North and East Bay. All of these areas are covered by National Weather Service Red Flag Warnings, indicating critical fire weather conditions.

To support our customers during this PSPS, PG&E will open 21 Community Resource Centers (CRCs). For customers with power turning off this evening, CRCs will be open from 7 p.m. today (Wednesday, Oct. 21) until 10 p.m. All CRCs will operate from 8 a.m. to 10 p.m. through the event. These temporary CRCs will be open to customers when power is out at their homes and will provide ADA-accessible restrooms, hand-washing stations, medical-equipment charging, WiFi; bottled water, grab-and-go bags and non-perishable snacks.

Timeline for safety shutoffs

The de-energization will begin around 8 p.m. Shutoffs will continue throughout the evening, ultimately affecting a total of about 37,000 customers in portions of Alameda, Butte, Colusa, Contra Costa, Glenn, Humboldt, Lake, Napa, Plumas, Santa Clara, Shasta, Sonoma, Tehama, Trinity, and Yolo Counties.

Customer notifications—via text, email and automated phone call—began Monday afternoon (Oct. 19), approximately two days prior to the potential shutoff. Additional notifications one day prior to the event took place Tuesday, Oct. 20. Customers enrolled in the company’s Medical Baseline program who do not verify that they have received these important safety communications will be individually visited by a PG&E employee with a knock on their door when possible with a focus on customers who rely on electricity for critical life-sustaining equipment.

Once the weather subsides on Friday morning and it’s safe to do so, PG&E will patrol the de-energized lines to determine if they were damaged during the wind event and repair any damage found. PG&E will then safely restore power in stages and as quickly as possible, with the goal of restoring power to nearly all customers within 12 daylight hours after severe weather has passed.
